I just bought a RSM 500 used off of a guy that upgraded tanks. It came with two MP40's, RSLL skimmer, and a PhosBan Reactor 150. I got it set up on Thursday night. I will be adding Pukani and Gulf live Rock with in a couple of weeks. The Pukani is curing in another tank at the moment, and I will be ordering the Gulf live rock soon. The wife did not want the smell of the rock curing in the house. I love the tank so far!
